8-BIT
8ASTERD

The 8-Bit 8asterd, running in your browser. Nine voices of chiptune across three emulated AY-3-8910 chips, with effects built out of what those chips do when you push them past their limits — the crushing and glitching is the hardware straining, not something added on top. This runs the real firmware compiled to WebAssembly, the same code that is on the physical unit. Press Start Audio, then play it from the chord matrix, the keyboard, the sequencer or a game controller.

chords + harp

Seven roots around the circle of fifths, three chord types, and a strumpad whose twelve notes follow whatever chord is held. Works with a mouse, a finger, or the letter keys.

Sequencer

16 steps

Sixteen steps of drums. Tap the row name to audition a sound. Everything the Drums and Drum FX sections do applies while it runs, so this is the quickest way to hear what Roll, Chaos or a Warp mode actually do to a pattern.

A password carries the settings alone — short enough to read aloud or print on a card. Save Game carries everything else.

Playback

No file loaded. Channel 10 plays the drum kit; every other channel goes to the tone voices, so every setting on this panel shapes the playback — temperament, envelope, unison, the Warp Zone, all of it.
